5.1.6 Consumed energy primary counter sending condition
The
“Consumed energy primary counter sending condition”
parameter defines the conditions for sending
the current primary counter value. The values that can be set are:
-
sending on request
-
sending on variation
(default value)
-
sending periodically
-
sending on variation and periodically
Selecting
sending on variation
or
sending on variation and periodically
,
visualises the parameter
“Consumed energy primary counter variation for sending”
whereas selecting
sending periodically
o
sending on variation and periodically
visualises the parameter
“Consumed energy primary counter
sending period (minutes))”
.
If
sending on request
is selected, no new parameter is enabled because the primary counter value is not
sent spontaneously by the device; only in the case of a status read request (e.g. from a supervisor) will it send
the user a telegram in response to the command received, giving information about the current value of the
primary counter.
If the sending condition of the primary counter is different from
sending on request
, the value of the counter
is sent after a BUS voltage reset in order to update any connected devices.
5.1.7 Consumed energy primary counter variation for sending
The
“Consumed energy primary counter variation for sending”
parameter is visible if the primary counter
value is sent with a change. It defines the minimum count variation (in relation to the last value sent) that
causes the new value to be spontaneously sent. The values that can be set are:
-
10 Wh
-
20 Wh
-
50 Wh
(default value if the counter format is “Wh”)
-
100 Wh
-
200 Wh
-
500 Wh
-
1000 Wh
(default and ONLY value that can be set from the database if the counter format
is “kWh”)
5.1.8 Consumed energy primary counter sending period (minutes)
The
“Consumed energy primary counter sending period (minutes)”
parameter is visible if the primary
counter value is sent periodically. It defines the frequency for spontaneously sending telegrams indicating the
current primary counter value. The values that can be set are:
-
from 1 to 255 in steps of 1
(default value 15)
In the event of a voltage failure, the primary counter value is saved in a non-volatile memory so it can be reset
when the power supply returns.
5.1.9 Reinitialize consumed energy counters
If the device configuration needs to be updated, and the ETS database downloaded again, you can indicate
whether the energy counter value (primary and differential) must be reinitialised or not via the
“Reinitialize
consumed energy counters”
parameter. The values that can be set are:
-
no
(default value)
-
yes
By setting
no
, the counter values are saved in a non-volatile memory and reset when the device is relaunched.
